Investigation of method of gastroenteritis treatment of stores by means of application of enterosorbents was realized in the conditions of the Republic of Belarus. For the experiment there was used preparation Lactofiltrum containing 80% of hydrolyzed lignin and 20% of lactulose applied in dose of 0,3 g/kg once a day during 7 days. Efficiency of application of Lactofiltrum was compared with enterosorbent SV-2, which contained alcaline hydrolyzed lignin applied in dose of 1 g/kg once a day during 7 days. Four experimental groups piglets sick with gastroenteritis in the age of 1,5-2 months, with body weight of 15-17 kg were used in the experiment. The first group piglets were entered 0,3 g/kg body mass of Lactofiltrum once a day during 7 days. The second group piglets were entered enterosorbent SV-2 in dose of 1 g/kg in course of 7 days. For the piglets of the third group there was applied the complex of analysed preparations in same course of treatment. The fourth group of piglets was entered enrotim 10% in dose of 1 ml/ 20 kg of body mass. All animals had the same conditions of feeding and keeping. Research results showed that application of Lactofiltrum, SV-2 and their complex provided high antioxidative, detoxification, gepathoprotective activities. These preparations proved to be effective means of pathogenetic therapy for the treatment of gastroenteritis of piglets, both as individual preparations, and complex application. Comparative estimation of treatment methods of gastroenteritis showed that these preparations (except enrotim 10%) made it possible to regulate the metabolic processes due to elimination of intoxication, positive influence on hematopoiesis. The preparations lowered the duration of clinic manifestation of a disease and facilitated its duration, had gepathoprotective and antioxidative activity

Results of studying the local of irritating properties of preparative forms of marsh cinquefoil (Comarum palustre) which were intended for treatment of parasitic of diseases of animals, namely, strongylatosis of gastro-intestinal tract of sheep and calves realized in the conditions of the Republic of Belarus were presented. Preparative forms of Comarum palustre (liquor, tincture, liquid extract and powder) had poorly expressed irritating properties after application into skin of animals and weak irritating action, excluding native forms of tincture and liquid extract on mucous coat eye, that confirms their low toxicity action as a whole on organism of animals.

For the determination of efficiency of a new produced in the Republic of Belarus preparation Ehkvikar there was modeled a test with a diaphoresis of guinea pigs by means of their staying in a thermostat at a temperature of 45-50 deg C in course of 30 minutes. Before and after the test there was taken a blood test for its analysis. Results of the experiment showed that together with sudo the animals lost 1-2 % of their body. There was stated the increasing of all blood corpuscles as well as lowering in 1,3-1,47 times of such elements as chlorine, sodium, potassium, and also T lymphocytes and bursa-derived lymphocytes. Application Ehkvikar promoted the stabilization of biochemical and morphological parameters of blood, and also the immune status of laboratory animals. Thus, Ehkvikar preparation promoted the compensation of losses of electrolytes with sudor of guinea pigs and in future can be studied by an example of horses for completion of electrolytes losses in the conditions of increased physical exercises.

Development of a new national preparation for the preventive maintenance of cow mastitis, fissures of milking tubes skin of cow udder was realized in the conditions of the Republic of Belarus. The preparation Maz' Solnechnaya ("Unguent Solnechnaya") did not contain antibiotics, hormones and other synthetic components. Natural components of a preparation provide long anti-inflammatory action, stimulate local blood circulation, regeneration of epidermis and accelerate processes of healing of microtraumas. Besides it possesses high efficiency at preventive maintenance of mastitises at cows.

In article results of studying of efficiency and quality of poultry-fanning production under influence chitosan are considered. It is established that the preparation promotes safety increase on 0,5%, efficiency on 6% and biological value of meat on 20% at chickens whom gave to drink chitosan in a dose of 5 mg/goal from 32 day age it) comparison with the control. Such technological reception leads to decrease the receipt in an organism of a chicken of microtoxins, heavy metals, products of a metabolism of bacteria

Results of researches on studying influence separate and combination feeding fermented compositions Fekord-2004C and biologically active additive Oxide Peat on energy of growth and protective properties of an organism of pigs – deprivation are stated. It is established that enrichment of mixed fodder investigated by the fodder fermented additive Fekord-2004C at the rate of 0,15 kg on ton of mixed fodder in combination application with biologically active substance Oxide Peat in a doze of 1,0 kg on ton of mixed fodder promotes increase of growth rate of pigs on development and to decrease of the charge of forages on unit of a gain of alive weight and safety of pigs

Development of a production technology of a national anthelminthic preparation Triclafen (from benzimidazole group) on the basis of triclabendazole and fenbendazole was realized in the conditions of the Republic of Belarus. As a result of realized experiments it was found that the developed suspension corresponded the requirements of pharmacopoeial items and can be applied for veterinary practice. Composition of different components with wide action spectrum made it possible to apply it against ruminant animals.

Determination of chronic toxicity of a new selenium-containing preparation Aesel was realized in the conditions of the Republic of Belarus. There was realized endermatic administration of the experimental preparation to laboratory white mice. Studying of sensitivity of some organs and systems of mice and revelation of a degree of reversibility of processes caused by active substances of the drug was realized. The main clinical, pathomorphologic, biochemical, hematological changes in the organism of laboratory animals with induced chronic toxicity were determined.

Comparative effectiveness of application of SV-1 and SV-2 sorbents for preventive treatment of abomazoenterite of 1-2 month old calves was studied in the conditions of the Republic of Belarus. Research results showed that application of SV-1 and SV-2 sorbents rendered a positive influence on hematological and biochemical blood indexes, in particular, there was an increasing of hemoglobin level, albumins content, alkaline reserve, calcium and phosphorous in blood serum. They also rendered the stimulatory effect on natural resistance. The prophylactic effectiveness in experimental group was 100%, in a control one – 60%.

Results of chemical and toxicological estimation of an energized preparation, intended for increasing of performance ability and sports qualities of horses realized in the conditions of the Republic of Belarus were presented. The energized preparation included honey, lactalbumin hydrolyzate, pollen hydrolyzate, and teotropin. Chemical and toxicological estimation of the preparation included determination of physical, chemical and pharmacological compatibility of components of the preparation, acute and chronic toxicological characteristics, skin-resorbtive poison after single and long-term application at horse skin, topical-product-induced irritation and allergic action of the preparation. Research results showed that all components of the preparation were compatible among themselves. The preparation proved to be a low-hazardous substance (substance hazard category 4) and did not possess skin-absorptive, local-irritating and allergic action.
